Gomez, who split from Bieber earlier this year, is worried he will include her in the sequel to his hugely successful 3D movie "Never Say Never", which is expected to released around Christmas.

According to the sources, one of Gomez's friends told her that she is likely to be featured in the documentary because Bieber's team has been recording the footage for about a year.

"Gomez just wants to move on and she made it clear that she does not want to be in the movie, DVD extras or anything at all," femalefirst.co.uk quoted Gomez as saying.

A friend close to Gomez also hit back at reports that blamed her for Bieber's recent bad behaviour and insisted she hasn't been sending him mixed messages by texting him on a regular basis.

"Bieber just bugs Gomez and the only reason she picks up her phone is because it's easier than dealing with harassment. It's so typical that a man would blame a woman for the fact that he's ruining his life and it's stupidity," the source added.
